We start with 80 and we add 1 on the first day, 2 on the 2nd, 4 on the 3rd, etc..
Looking at the numbers being added
1 = 20
2 = 21
4 = 22
8 = 23
16 = 24

We start with 80 and we add 2n to it where n represents the number of days into the iteration
with n starting at 0
The function that shows how many stamps we have on any given day is
D
S = 80 + ∑ 2n Where D is the number of days we are into the iteration
n=0
NOTE: This starts at day 0 which would be S = 80 + 20 = 80 + 1 = 81 stamps
Example: To find how many stamps we have on D = 4 we would have
S = 80+20+21+22+23+24
= 80+1+2+4+ 8+16
= 111 stamps
Answer:
C) 36
Step-by-step explanation:
y = a(b^x) = a(1 + r)^x
Here, 1 + r = 1 + 0.36, so 0.36 is the rate.
0.36 = 36%
Answer: C) 36
Answer: the maximum is (-2,5 )and the equation for the axis of symmetry is x = -2
Explanation if you want:
for the min and max: when a quadratic has a maximum point, that is the largest point that it will ever be at. When it has a minimum, that is the smallest.
- the +5 tells us that we have an upward movement of 5. The +2 means we actually move to the point -2. bc: (x+2)=0 = -2
- so, from our initial function, those are the changes.
for the axis of symmetry: basically, this is the line that splits the graph into two equal parts.
- it is the line that goes through the vertex (which we already know is (-2,5).
there u go
